I bought three Powerball quick pick tickets today and I thought the distribution of the numbers I received was strange. It made me wonder if the Powerball quick pick tickets are truly random?

Remember: 3 tickets.

The number 21 showed up on all 3 tickets.
The number 37 showed up on two of the tickets.
The number 45 showed up on two of the tickets.

On three tickets, not counting the Powerball number, there are 15 possible different numbers. But on my three tickets there are only 12 different numbers.

Two tickets both have 21 and 37.
Two tickets both have 21 and 45.

Two tickets both have only one "birthday number" -- meaning a number under 32.

I think there are a lot of "repeaters" for only three tickets.
